For all the flaws Katy Perry has (and trust me, there are many), her acoustic/down-tempo songs are damn good.

They say you know when you know
I don’t know
I didn’t feel that fairytale feeling, no
Am I a stupid girl for even dreaming that I could?

If it’s not like the movies
Maybe that’s how it should be
When he’s the one I’ll come undone
And my world will stop spinning
And that’s just the beginning 

And sure I confess
I’m a mess, a mess of mistakes
